Got some more info today. Insurance company are acting rather odd.
They arranged for it to be taken into safe storage, before repair.
And now seem to be asking questions like they think it some sort of fraud.
They asked for pics of both keys. One of which is with the company who removed it for storage. Asked for details of how it was paid for new. WTF has that got to do with anything?
I've also seen pics of the damage done. Broken 1/4 light in the front door. Steering lock and cover. £500 max?
It seems they got it started by accessing the diagnostic port. Words fail me. But it is a Fiat.
